Stefan liked to solve puzzles and mathematical problems since he was little. Gradually he became lazier and his memory got worse than what he would like it to be. When he tries to calculate more than 2 moves ahead in chess, his head starts hurting. So he became interested in methods that help him plan his vacations, manage his schedule and budget, and prioritize projects and decide whether to buy a house. Stefan is currently Head of Research in Transmetrics, an Augmented Intelligence SaaS company, serving the needs of the transportation industry. The problems they work on involve trying to forecast the future, estimate the uncertainty, plan the best course of action given that, and give action recommendation that appeals intuitively to the expert user.
